FIELD: physics; control.SUBSTANCE: invention relates to automatic control systems for aerospace objects primarily operating in extreme environmental conditions. An automatic control system comprises series-connected sensor array, information collection unit, control computers and channel switch, controlled by a control unit. The control computers are connected to actuating elements of the control object. The automatic control system also includes a gimballess inertial navigation subsystem with corresponding sensors and (neural) computers. The automatic control system has, connected to the information collection unit, standard satellite navigation equipment and an original optical correction subsystem with sensors of different spectral ranges, microprocessor and other elements. The automatic control system includes a storage device which stores restart arrays for restoring operating capacity of control computers after a pulse of ionising or electromagnetic radiation. Parametric failures are fixed by a secondary (constant and pulsed) power supply controlled from the control computers by field-effect transistor circuits. All means of fixing catastrophic failures have internal backup with monitoring of operation thereof and switching to a properly operating channel.EFFECT: high reliability and accuracy of operation of an automatic control system for a long period of time in conditions of external destabilising factors and wider field of use of the automatic control system.28 cl, 30 dwg |
